(A) ;SYSTEM FOR ELIMINATING INTERFERENCE BETWEEN ORTHOGONALLY POLARIZED WAVES

摘要

PURPOSE:To prevent noises from occurring at the time of switching in the titled receiver which is provided with two pairs of antennas and reproduces voices by switching the receiving system to the one having larger electric field intensity, by installing comparators which correspond to the electric field intensity of each received wave to each receiving system. CONSTITUTION:A signal received through the 1st antenna is supplied to a multiplex circuit 16 through a wave detecting means 10 and a switching means 13. Another signal received through the 2nd antenna is supplied to the circuit 16 through another wave detecting means 11 and another switching means 14. To comparators 12 and 12', signals V1 and V2 which correspond to the electric field intensity of received waves are supplied from the 1st and 2nd antennas through a high frequency amplifying means. The comparators 12 and 12' turn on one of the switching circuits 13 and 14 in accordance with the size of the signals V1 and V2.
